A sub-dashboard skeleton

Abstract

A sub-dashboard frame, comprising a sub-dashboard frame body, the sub-dashboard frame body including a rear storage box, a side panel reinforcement structure, a bottom panel reinforcement structure and a middle frame, the front end of the rear storage box is connected to the The rear ends of the middle frame are connected, the side plate reinforcement structure and the bottom plate reinforcement structure are both arranged on the rear storage box, and the middle frame is provided with a middle reinforcement rib. The invention greatly improves the rigidity of the side wall of the rear storage box by arranging continuous side wall reinforcement ribs on the main body of the sub-instrument panel, avoids possible abnormal collision noises during driving, and simultaneously realizes light weight, molds and manufacturing processes Less difficult.

Description

technical field [0001] The invention relates to the technical field of automobile safety, in particular to an auxiliary instrument panel frame. Background technique [0002] The auxiliary instrument panel is located behind the instrument panel of the car, between the main driver's seat and the passenger seat, its front part is connected with the instrument panel, and its lower part is overlapped with the car floor. The sub-dashboard is usually equipped with operating equipment such as shift levers, operating buttons, and joysticks, and the rear part is usually equipped with storage spaces such as rear storage boxes and water cup holders. The sub-dashboard covers a large area and has a lot of internal space. It is an important part of the car interior. [0003] Usually, when designing the sub-dashboard frame, after the definition of the storage space is completed, the lateral stiffness of the structure is mainly increased by adding reinforcement ribs to the side wall of the ...

Problems solved by technology

[0003] Usually, when designing the sub-dashboard frame, after the definition of the storage space is completed, the lateral stiffness of the structure is mainly increased by adding reinforcement ribs to the side wall of the rear storage box or adding fixed points on the side of the rear storage box. However, the existing sub-dashboard structure often has the following problems: the rear storage box has insufficient lateral rigidity, and it is easy to shake and produce abnormal noise during driving or when touched; Too much material is used, which is not light enough; the bottom surface of the rear storage box is not rigid enough, which is prone to torsion; when the rear storage box is far from the installation point of the body floor, the structure at the installation point is weak and the connection structure is not rigid enough, which is prone to side swing ; The frame in the middle of the sub-instrument panel is not rigid enough to connect and support the rear storage box
